Why did each group test the amount of drops of water a penny could hold before changing their variable?

• It provides more data to include in a lab report
• It ensures that the hypothesis will be correct
• It adds an independent variable to the experiment.
• It is the control and serves as the basis for comparison

How many variables should be changed in an experiment?

• ONE
• TWENTY
• THREE
• TEN

Group 1 found food coloring affects the amount of drops a penny holds.  Group 2 found that food coloring does not.  What should they do?

• Ignore Group 2
• Conduct it again with quarters
• They should repeat the experiment again and compare results
• Conclude that food coloring has no effect
